Description
Technical field
The utility model belongs to industrial air-conditioning field, and in particular to a kind of mutually to be tied using plate heat exchanger with spray row of tubes
It closes, carries out the novel combined air conditioning group of heat exchange.
Background technique
In traditional unitary air handling unit, heat exchange is that 7 DEG C made from refrigerator/cold source of chilled water is passed through guarantor
Pipeline after temperature is sent into the copper pipe of the surface air cooler in unitary air handling unit, and unitary air handling unit is by sky to be treated
The effect by blower is adjusted, with certain flow velocity by the copper pipe of surface-type heat exchanger and the outside of cooling fin, to make air-conditioning
Cooling, while 7 DEG C of chilled water for entering surface exchanger is increased to 12 DEG C and returns in refrigerator because obtaining heat, temperature,
Air after obtaining cooling capacity cooling is sent to each air-conditioning place by unitary air handling unit.
The heat exchange mode of surface-type heat exchanger has the following deficiencies: in existing unitary air handling unit
1 surface-type heat exchanger manufacturing cost is high
Surface-type heat exchanger is by copper pipe, aluminium foil, seamless steel pipe and galvanized sheet frame composition, with copper material, the valence of aluminium
Lattice rise steadily, so that the manufacturing cost of surface-type heat exchanger constantly increases.
Secondly the unitary air handling unit of surface-type heat exchanger, the maintenance function that must be stayed due to the front and back of heat exchanger are used
Section and maintenance door so that the length of air-conditioner set increases cause the increased costs of unit casing, frame.
2 air-conditioner set energy consumptions are higher, increase the operating cost of air-conditioner set.
Due to the special construction of surface-type heat exchanger, air to be treated passes through surface-type heat exchanger in air-conditioner set
When, very big resistance can be encountered, this will drive the motor of the blower in air-conditioner set to improve power, to overcome air to pass through
The resistance encountered when surface-type heat exchanger is generally in 300Pa to 500Pa.
Secondly as surface-type heat exchanger is many by elbow, chilled water flow through resistance that surface-type heat exchanger encounters compared with
Greatly, and conventional chilled water to send coolant-temperature gage back to be 7 DEG C -12 DEG C so that chilled water water is larger, increased chilled water is sent back to
The power of water water pump causes the operating cost of water pump to increase.
Again, the cooling fin of surface-type heat exchanger due to by air processed dust and oxidizing property influenced,
It causes aluminium flake to corrode, influences heat transfer effect, increase the refrigeration duty of refrigerator.
The maintenance cost of 3 air-conditioner sets is higher
The air of heat exchanger is by gap very little on surface, and when combined air conditioner unit handles air, dust therein is easy
The blocking between surface-type heat exchanger cooling fin is caused, needs both to increase maintenance cost to surface-type heat exchanger periodic cleaning,
Sometimes the normal operation of air-conditioner set has also been delayed.
4 service life are short
When passing through surface-type heat exchanger due to air-conditioner set processing air, the dust and oxidation material of entrainment be easy to cause scattered
The corrosion of backing, so that aluminium flake aoxidizes, so that the reduced service life of surface-type heat exchanger.
